It would be helpful for the current generation of smaller electic vehicles that are fine for daily use but would need to stop every 100 miles on a longer trip in winter.
I have driven a leaf since 2016 and I can tell you that no one will do this with 100 miles between stops. Because the stops aren't at exact intervals, you might be stopping every 80 to 90 miles since you don't want to risk not getting to the next.
At that rate, you're adding time really quickly as charging might take 8 minutes but getting to and from the charger easily adds another 4 to 8 minutes. At that point you're talking about adding about 10 to 16% to your total time taken
The listed range of the car that I'm thinking of [0] is 186 miles, I was using 100 miles as the useful range in winter as there are reports that it drops by a lot in the cold, this vehicle gets the largest subsidy in the UK right now. I had been considering this as my next car even before the subsidy was announced but slightly more range would be nice.
